EC MOTORS
Domel has been independently developing EC motors since
1986. Over the years we have gained the knowledge and expertise
of key motor technologies (stamping and molding) and enriched
core R&D competences in electromagnetics, aerodynamics, acous-
tics, rotodynamics, power electronics, rapid prototyping and testing.
With all the in-house knowhow Domel is now present in various
markets where EC technology is becoming more and more no-
ticeable. Some of the applications where you can find Domel’s EC
motors are HVAC systems, gardening appliances, power tools, au-
tomotive components, white goods, vacuum cleaners, fume/smoke
extraction devices, boilers, handling devices, medical and labora-
tory equipment, and much more…
Increased awareness about energy savings lead Domel to develop
EC motors and controllers for HVAC industry, which is one of the top
leading users of electricity consumption. In 2009 serial produc-
tion of EC motors, named AZ motors, was industrialized.
When developing highly efficient AZ motors, we placed consider-
able emphasis on the optimum use of materials, state-of-the-art
technology and long-life operation. The excellence of these mo-
tors is further enhanced by their high capacity and strongly wear-
resistant housing, optimal coordination between the motor and
controller, and the monitoring of the rotor position without Hall sen-
sors. They require no maintenance since, with the exception of the
bearing system, they do not contain any mechanical parts which are
susceptible to wear and tear. The motors are highly efficient (up to
a level of approx. 95%) and have an excellent power capability. It is
worth adding that AZ motors are extremely compact with very short
bed length.

ENVIRONMENTAL CARE
In an era of rising energy prices, concerns about reliance on gas, cli-
mate changes and environmental taxes, the awareness of the impor-
tance of the environment and energy saving has never been higher.
Naturally, this trend is not only driven by increased awareness about
energy saving, but also as a result of international political activities,
which are becoming increasingly stringent.
Heating, ventilation and air conditioning are among the five leading
users of electricity consumption. Domel followed the trend in con-
tributing to energy savings and, in 2009, commenced with the serial
production of EC motors specifically designed for HVAC applications,
named AZ motors. These motors adhere to the regulations and direc-
tives for motor efficiency requirements and guarantee enormous en-
ergy savings and hence improved Return on Investment. The
products exceed the IE4 Super Premium efficiency class and, in ac-
cordance with the newly proposed standard, also fulfill the criteria for
the IE5 Ultra Premium efficiency class (according to IEC 60034-30).
When purchasing a motor driven system, lifetime costs are of con-
siderable importance. To only compare purchase prices is a false
economy which overlooks the considerable financial benefits of the
lower operating costs that may be achieved with a more efficient
and quality system.
Our motors reduce operating costs by working at very high level
of efficiency within a wide speed and power range. Ad-
vanced technology and state-of-the-art equipment assures highest
quality and long lifetime of the product with maintenance-
free operation.
In comparison to standard AC motors in the IE2 High efficiency class,
annual production of Domel’s AZ motors additionally saves more than
100 GWh of electricity each year, which is comparable to the annual
supply of a medium-sized hydro power plant.
